Amazon "Seamless white background" Patent.

Do you think Amazon will really go after the little guys who may have already used a similar technique? (I'm really asking here). I'm not sure what Amazon's history is of going after smaller companies. I mean, I don't want to be naive and fully believe that they patented the setup to only protect themselves from someone else patenting it and suing them, I'm sure there is more in it for them.

This whole things just seems ridiculous though. On one hand I can understand Amazon's stance in saying it wants to protect itself, but this? WTF.
